Not always. For example, I went ass over tea kettle down a slope last year and dinged the turret on my Razor LHT.
The scope bounced off rocks for a good tumble and is completely fine, save for the external marks - the turrets track fine and the glass shows no signs of issues. However, I have no doubt in my mind that I could send it to Vortex, and they’d send me a new scope, if something did go wrong.
Shit happens - Binoculars take tumbles and rifles fall. I’d rather have a brand that stands by their product, regardless of cause, than one that tells me to pound sand.
